Thanks everyone for your replies. Ok, I fired a projectile that took 2.46s to go 8.86m. Therefore I plotted the points (0,0) [because at t=0, the displacement was 0m], (1.23,4.43) [because 1.23s is the turning point of the projectile ie v=0, and thus the displacement will be half the total...

Hi lackos, I got the equation by taking the second derivative of the equaton I formed for the displacement over time of the projectile. I know it has a time dependent variable and this is what is confusing me. I am beginning to think that I somehow didn't form the displacement over time...

Sorry, I am trying to find the initial vertical velocity, ie the vertical velocity at time(t)=0. equation for the acceleration of the projectile is a=14.28t+17.56 initial velocity=10.8m/s, ie v=10.8 @t=0; when v=0 (projectile at maximum height), t=1.23; displacement of projectile at t=1.23 is...

Hi everyone, I am just starting to get into using physics and calculus, and have just been doing my own experiments to understand the concepts etc better. I have formed an equation for displacement against time for a projectile and have differentiated it to get equation of velocity, then...
